AP65550SP-13

Overview

The AP65550SP-13 is a synchronous step-down DC/DC converter manufactured by Diodes Incorporated. It operates with an input voltage range of 4.5 V to 18 V and delivers up to 5 A of output current. The device features a fixed switching frequency of 650 kHz and provides an adjustable output voltage from 760 mV to 6 V. It utilizes adaptive constant on-time (COT) control architecture for transient response optimization. The component supports shutdown functionality and includes comprehensive protection mechanisms against overcurrent, overvoltage, and thermal conditions.

Feature Summary

Adaptive Constant On-Time (COT) control topology
Integrated synchronous rectification
Built-in thermal and overcurrent protection

Applications

Point-of-load regulation in industrial systems
Power supply stages for embedded computing modules
Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix designation during procurement. Official documentation lists the model AP65550FN-7 with U-DFN3030-10 packaging. Confirm that the requested SP-13 variant matches the required SOIC-8EP package configuration. Ensure compatibility with automotive or industrial temperature grades if specified in the design requirements. Cross-reference datasheet revisions to confirm pinout consistency before integration.

Selection Notes

Select this component when a high-current buck converter is required within an 18 V input limit. The 650 kHz frequency allows for moderate passive component sizing compared to higher-frequency alternatives. Consider the thermal performance of the SOIC-8EP package for heat dissipation needs. Evaluate the need for external compensation versus internal loop stability provided by the COT architecture.

Part Context

This part belongs to the AP65550 series of synchronous buck converters from Diodes Incorporated. The series targets applications requiring efficient power conversion with minimal external component count. The manufacturer emphasizes reliability through integrated protection features and robust control loops suitable for demanding environments.
